WEEK 1
Introdução a redes
Bem-vindo ao curso de redes da Certificação Profissional em Suporte de TI! Na primeira semana do curso, veremos os conceitos básicos das redes de computador. Falaremos sobre os modelos de rede TCP/IP e OSI e veremos como as camadas da rede trabalham juntas. Além disso, abordaremos noções básicas dos dispositivos de rede, como cabos, hubs e switches, roteadores, servidores e clientes. Analisaremos em mais detalhes a camada física e a camada de enlace de dados do nosso modelo de rede. Ao fim deste módulo, você saberá como todas as diferentes camadas do modelo de rede se relacionam para criar uma rede.

WEEK 2
A camada de rede
Na segunda semana do curso, analisaremos a camada de rede em mais detalhes. Veremos o esquema de endereçamento IP e como as sub-redes funcionam. Vamos entender como o encapsulamento funciona e como protocolos, como o ARP, criam as condições para que diferentes camadas da rede se comuniquem. Além disso, estudaremos conceitos básicos de roteamento, protocolos de roteamento e veremos como a Internet funciona. Ao fim deste módulo, você conseguirá descrever o esquema de endereçamento IP, explicar como as sub-redes funcionam, realizar cálculos binários para descrever sub-redes e explicar como a Internet funciona.

WEEK 3
As camadas de transporte e aplicação
Na terceira semana do curso, falaremos das camadas de transporte e aplicação. Ao fim deste módulo, você será capaz de descrever portas TCP e soquetes, identificar os diferentes componentes de um cabeçalho TCP, mostrar a diferença entre protocolos orientados a conexão e sem conexão e explicar como o TCP é usado para garantir a integridade dos dados.

WEEK 4
Serviços de redes
Na quarta semana deste curso, vamos explorar os serviços de redes. Saberemos por que precisamos do DNS e como ele funciona. Também mostraremos por que o DHCP facilita a administração de redes. Até o fim deste módulo, você conseguirá descrever como funcionam o DNS e o DHCP, como as tecnologias NAT ajudam a manter as redes seguras e como as VPNs e os proxies ajudam os usuários a se conectar e a se proteger.

WEEK 5
Conexão com a Internet
Na quinta semana deste curso, exploraremos a história da Internet, como ela evoluiu e como ela funciona hoje. Vamos entender as diferentes maneiras de se conectar à Internet por meio de cabos, conexões sem fio, por celular e até mesmo conexões com fibra. Até o fim deste módulo, você conseguirá definir os componentes das WANs e delinear os conceitos básicos de uma rede sem fio e de celular.

WEEK 6
Solução de problemas e o futuro das redes
Parabéns, você chegou à última semana do curso! Na última semana deste curso, falaremos do futuro das redes de computadores. Também cobriremos os aspectos práticos da solução de problemas de uma rede usando os sistemas operacionais mais comuns. Até o fim deste módulo, você conseguirá detectar e corrigir muitos problemas comuns de conectividade de rede usando as ferramentas disponíveis nos sistemas operacionais Microsoft Windows, MacOS e Linux.
